Tight Ducts | PSO ENERGY STAR Homes

Tight Ducts

In your high-performance home, tight ducts ensure that your attic is not as cool as the rest of your house. In many code-built homes, up to 30 percent of energy loss can be directly attributed to a leaky duct system. High-performance homes are inspected and tested to ensure that sealing around joints in the duct system are sealed tightly so that conditioned air does not leak into storage spaces such as attics and garages or within the wall cavity. Ducts that are sealed tightly are less likely to pull apart letting conditioned air out or unconditioned air into the duct system. This reduces the potential for dust and pollen to infiltrate your indoor air.

Benefits of Tight Ducts: Not only will Tight Ducts contribute to lower utility bills - they will also improve the quality of air in your home and help maintain a uniform temperature throughout.
